Cauchy Distribution • The formula for the probability density function of the Cauchy distribution with (Theta,1) is: f(x)=1/[pi(1+(x-Theta)^2]
Log Likelihood function Log Likelihood function is : SUM(log(1/(pi*(1+(x-t)^2)))) First derivative: Sum(pi * (2*(x-t))/(pi*(1+(x-t)^2))^2/(1/(pi*(1+(x-t)^2)))) Second derivative is : 2*sum(((x-t)^2-1)/(1+(x-t)^2)^2)
